Summary: Move Flink Calcite rules from Scala to Java Key: FLINK-34156 URL: https://issues.apache.org/jira/browse/FLINK-34156 Project: Flink Issue Type: Technical Debt Components: Table SQL / Planner Reporter: Sergey Nuyanzin Assignee: Sergey Nuyanzin Fix For: 2.0.0 This is an umbrella task for migration of Calcite rules from Scala to Java mentioned at https://cwiki.apache.org/confluence/display/FLINK/2.0+Release The reason is that since 1.28.0 ( CALCITE-4787 - Move core to use Immutables instead of ImmutableBeans ) Calcite started to use Immutables (https://immutables.github.io/) and since 1.29.0 removed ImmutableBeans ( CALCITE-4839 - Remove remnants of ImmutableBeans post 1.28 release ). All rule configuration related api which is not Immutables based is marked as deprecated. Since Immutables implies code generation while java compilation it is seems impossible to use for rules in Scala code. -- This message was sent by Atlassian Jira (v8.20.10#820010)
